Great apartment. I stayed here with 4 other people for 4 weeks and we had space to spare. Very large living area and master bedroom. Pictures looked exactly like the ones advertised on Airbnb.
The staff are very attentive and welcoming - someone is always at the front desk 24/7 so there was no concerns about having one room key between 5. Very easy to contact them if you need anything such as extra towel or toilet paper. 6 bottles of water were left in our fridge every day.
Kitchen has some utensils but be aware no oil, seasoning etc.
Gym, pool, basketball and tennis court were all a nice addition - be aware, there is a charge for renting pool towel and for the tennis equipment.
Great location in the Silom area - near a BTS station and walking distance to a MRT station. Plenty of restaurants on your door step.
Inthanom was a great host and I would definitely recommend staying here.
